Abstract
Patients with heart failure undergoing cardiac rehabilitation are aging in accordance with the general Japanese population. It is important to understand the risk of falls in these patients. The aim of this study was to identify factors predictive of fall risk in elderly patients hospitalized for heart failure. We enrolled 33 elderly patients admitted to hospital for heart failure, divided them into two groups (with or without fall risk according to the Berg Balance Scale), and compared patient characteristics, disease severity, and physical function between the groups. We then performed logistic regression analysis to identify the factors related to fall risk, and cutoff values were calculated using receiver operating characteristic curves. Six-minute walking distance (6MWD) was the only independent predictor of fall risk. The cutoff value was 328 m. The results of this study suggest that fall risk is increased in this patient group when 6MWD is < 328 m. 要旨:人口の高齢化に伴い,心臓リハビリテーション対象者も高齢化しており,転倒リスクを評価することの重要性が 高まっている.そこで,本研究は,転倒リスクをスクリーニングするための項目を検討することとした.60 歳以上の入 院高齢心不全患者 33 例を Berg balance scale を使用して,転倒リスクの有無で 2 群に分け,患者背景,重症度,身体 機能を比較した.その後,ロジスティック回帰分析を行い,転倒リスクの有無に関連のある項目を抽出し,ROC 曲線を 用いてカットオフ値を算出した.転倒リスクに独立して関連する因子は 6 分間歩行距離のみであり,カットオフ値は 328m であった.6 分間歩行距離が 328m 未満では転倒リスクが高い可能性があることが示唆された. キーワード:高齢心不全,転倒リスク,スクリーニング
